The diversity of effects of mosquitofish underscores the difficulty of predicting the impact of #bioinvasions. We further provide an approach to differentiate the effects of resource competition from other more direct ecological interactions & so to clarify the impact mechanism of #bioinvasions. 🌎

The experiment also demonstrated that the interspecific effects of mosquitofish on toothcarp were more important than those of intraspecific competition. The invasive species produced effects on population growth rate, size structure, and fish condition (mass-length relationship) of toothcarp.

At high fish densities, turbidity, chlorophyll a concentration and daytime dissolved oxygen percentage increased, whereas total phosphorus decreased; crucially, the trophic cascade caused by mosquitofish was stronger than that by toothcarp.

Muy contento de liderar hasta ahora esta Red #InvaNET (RED2018‐102571‐T y RED2022-134338-T) de excelentes grupos de investigación sobre especies invasoras @greco-udg.bsky.social @iea-udg.bsky.social @ebdonana.bsky.social @imedea.bsky.social @annatraveset.bsky.social @ceabcsic.bsky.social...

En el bienio 2025-2027 realizaremos el primer escaneo de horizontes de especies invasoras para las islas Baleares y completaremos la primera lista actualizada de las especies exóticas establecidas en España, una base de datos que es sumamente necesaria para la toma de decisiones.

Privileged to listen two excellent Mozart piano concertos last Sunday in Girona by Sir András Schiff and Cappella Andrea Barca. A pianist I mostly admire and likely the best pianist I ever heard live.

I’m teaching ecological succession these days and had a lot of fun rereading these sentences from the outstanding, beautiful Margalef’s ecological treatise, a book likely neglected by those not reading Spanish. Hopefully, the students will like the following sentences tomorrow:

Just joined Bluesky. I'm a inland fish ecologist at the University of Girona, mostlly working on invasive species. Very disappointed of what happened to the other social network, which was great to learn things, build a scientific community and make outreach. Hopefully Bluesky will replace it.
